Description

This second hand pedal is in very good condition for it's age, even has the original box!

Some tarnishing on the metal finish, but otherwise great

Circa 1970s

 

The original Electro-Harmonix Octave Multiplexer, released in the late '70s, is a gritty, glitchy, and gloriously gnarly analog octave-down pedal that’s earned a place in the hearts of fuzz freaks and synth-bass seekers alike. If you crave raw, analog attitude with unpredictable flair, read on.

Sound & Character:

The Multiplexer isn’t subtle. It delivers a thunderous, synthy sub-octave with a distinctive growl. Unlike modern digital octavers that track everything smoothly, the Multiplexer leans into its analog quirks. It has a monophonic voice and works best with single-note lines (think stoner rock riffs, doom chugs, or funky bass runs). Play chords or let it get confused, and it rewards you with chaotic, sputtery weirdness—in the best way possible.

Controls:

  • Blend: Balances your dry signal with the sub-octave. Cranking the sub creates a huge, almost synth-like tone.

  • Bass Filter: Shapes the sub-octave tone, giving you everything from a wooly rumble to a tighter, snappier growl.

  • High Filter: Tailors the high-frequency content of the dry signal, letting you push the mids or smooth the edges.

The filters are simple but effective, and part of what makes this pedal so special is how interactive the controls are. You can dial in a tight, bass-focused rumble or go full-on fuzzed-out chaos.

Build Quality:

The vintage units are built like tanks—chunky enclosures, heavy-duty switches, and that unmistakable retro EHX aesthetic.

Use Cases:

  • Guitarists looking for a fuzz-friendly sub-octave for riffs and leads.

  • Bassists wanting to add synthy depth or get pseudo-synth tones.

  • Experimental/noise musicians who appreciate unpredictability and grit.

Pros:

  • Huge, gnarly analog sub-octave sound.

  • Unmistakable character and vintage mojo.

  • Fun for fuzz-stacking and weird textures.

 

Verdict:

The original Electro-Harmonix Octave Multiplexer is not a precision tool—it’s a vibe machine. It adds analog warmth, unpredictable grit, and monstrous low-end in a way that no clean digital pedal can truly replicate. it’s a true underground gem.
